GPS Autonomous Micro-Monitor

ASTRA’s next generation GPS monitoring instrument combines all the world-class features of our CASES SM-211 units with exciting new functionality including the ability to reliably operate in oceanic environments where wave motion historically hindered accurate data acquisition.

Traveling Ionospheric Disturbance (TID) Mapping System

ASTRA’s TIDDBIT HF sounder is a dual-frequency HF Doppler system that can detect and characterize waves propagating through the ionosphere. Using spaced transmitters and receivers operating at multiple frequencies, this unique instrument resolves both horizontal and vertical propagation characteristics.
